Specification of Letters Patent.

Patented June 6, 1916.

Application filed May 19, 1915. Serial No. 29,247.

To all whom it may concern:

-Be it known that I, MANUEL Sous, citizen of the Republic of Cuba, residing at No. 541 Cerro, in the city of Habana and Republicof Cuba, have invented certain new and useful Improvements in Bench-Dogs, of which the following is a specification.

My invention relates to a bench dog attachment to a work-bench in which the dog is adjustable for length of work and held in adjustment by a clamp-screw, and is also operated by the threads of said screw to clamp said work.

I have illustrated an embodiment of my invention in the drawings, and with reference to same: Figurel, is a perspective view of a bench with my dog device applied; Figs. 2, and 3, are perspective views from different angles of the dog device detached.

My device is to be used with a work-bench A, having a slot B, therethrough, and comprises a guideway which may be formed of two parallel barsC, C, having upper opposed rabbeted edges, the rabbets forming grooves when the bars are secured to the under side of a bench. A block K, is placed between the bars and may have flanges en-' gaging said rabbets and has a part spanning the bars and engaging their lower face. This block has threaded through it a screw L, the upper end of which has a clamp-head N, which may be forced up against the underside of the bench to hold the block K, in adjusted position according tothe length or position of the work upon the bench A.

A lever I, is pivoted to the block K, as at 0, so that it may extend through the slot B, in the bench A, and has at its upper end a transverse head H, with a dogging edge which may be toothed or plain. Said lever I, also extends below its pivot O, and transversely to and adjacent the screw L, which it may be forked or slotted to embrace, as shown at Y. A nut M, on the screw L, is arranged to engage this part of the lever and its adjustment will tilt the lever to bring its dogging head H, into engagement with the work.

D is a board or cross piece to give strength to the weakest part ofthe bench, and prevent the dog from escaping backward from the bench and J is a piece of wood to be worked. v

Y, represents the curved forkedlower.

branches of the lever I and P, the thumb piece of the screw L.

I claim? A bench dog device, comprising a guideway, a block slidingtherein, a screw in said block for clamping said block in adjusted position in said guide-way, a lever carried by said block and having one end adapted" to dogand hold the work, and means engaging the thread of said screw for operating the lever into engagement with the work.

In testimony whereof I aifiX my signature in presence of two witnesses.

I MANUEL SOLIS.
